Question

A water sample is collected. The water is in equilibrium with the atmosphere. The K_H for CO₂ is 10^-1.5. Assume the CO₂ content of the atmosphere is 400 ppm. The sample has a pH of 6.5. The pK_a1 for H₂CO₃^* is 6.3 and its pK_a2 is 10.3.

The alkalinity (in units of eq/L) of the water is:
